Plasters; (consisting of calcined gypsum or calcium sulphate), whether or not coloured, with or without small quantities of accelerators or retarders

HS code 252020 covers plasters consisting of calcined gypsum or calcium sulphate, which are widely used in the construction industry. These plasters are essential materials for a variety of applications, including wall and ceiling finishes, moulding and casting, and as a binder in the production of building materials. The global plaster market is expected to grow steadily in the coming years, driven by increasing construction activities, particularly in developing economies.

The production of plasters under HS code 252020 typically involves the calcination of gypsum or calcium sulphate. This process involves heating the raw materials to high temperatures, which drives off the water molecules and leaves behind a fine, powdery material. The plaster may then be mixed with small quantities of accelerators or retarders, which can be used to control the setting time and other properties of the final product.

The main raw materials required for the production of plasters under HS code 252020 are gypsum or calcium sulphate. These materials are often mined or extracted from natural deposits. In addition, manufacturers may use various additives, such as accelerators or retarders, to modify the properties of the plaster. The production process also requires specialized equipment, such as calcination furnaces and mixing machinery.

Plasters produced under HS code 252020 are primarily used in the construction industry for a variety of applications, including wall and ceiling finishes, moulding and casting, and as a binder in the production of building materials. These plasters may be consumed by manufacturers of 441830 Building boards of wood, agglomerated with mineral binders, 681190 Articles of cement, of concrete or of artificial stone, n.e.c. and 682410 Ceramic building bricks, flooring blocks, support or filler tiles and the like.
